Upgrade your compressor's performance with this heavy-duty 25 Amp air compressor 4 Port pressure switch. Built to handle high startup loads and eliminate common issues like burnt or melted contacts, this switch is a reliable choice for replacement or upgrade. It’s compatible with a wide range of air compressors and great replacement switch for Furnas, Square D, Sunny, Lefoo, and others.

Pre-set to activate at 140 PSI and shut off at 175 PSI, this unit also allows you to adjust the pressure range between 60 PSI and 200 PSI to suit your system’s needs. The integrated unloader valve helps maintain consistent startup performance by reducing tank pressure on restart.
